OIL-IBURNER.

Specification of Letters Patent.

Application filed March 13, 1912. Seria1.No. 683,525.

To all whom it may concern:

Be it known that I, WILLIAM R. Cool-IRAN, Jr., a citizen of the United States, residing at Toledo, in the county of Lucas and State 5 of Ohio, have invented certain new and use ful Improvements in Oil-Burners; and I do hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the 'art to which it 'appertains to make and use the same. T

My invention relates to an improvement in oil burners, the object being to rovide an oil burner for stoves or other heatmgapparatus which will be simple, economical and durable in its construction and of high efficiency in its operation.

With. these objects inview my invention consists in certain features of construction and combinations of parts as will be here-.

inafter described and pointed out in the claims.

In the accompanying drawings, Figure 1' is a view partlyin transverse section and partly in end elevation of one embodiment of my improvement; Fig. 2 is a View inside elevation of my improved burner detached from the stove; Fig. 3 is a view in end elevation of the burner; Fig. 4 is a view partly in side elevation and partly in longitudinal section of the burner and its supporting frame; Fig. 5 is a transverse sectionof the burner and Fig. 6 is a plan view of the same.

1 represents a supporting frame consisting of the side plates 3, top plates 2:"and end plates 4. The top plate is provided with ribs 2 so as to form a tray 2* to receive dripping, etc. The. burner comprises two parallel pipes 5 and 6. The lower pipe 5 is 40 preferably of smaller diameter than the upper pipe, and is supported in vertical grooves 7 formed in the transverse deflector plates 8 by which they are retained against accidental displacement. Pipes 5 and 6 are connected at one end by means of the elbow pipe couplings 9, which fit between the inwardly projecting flanges '10 integral with one end platef4 of the supporting frame.

which are separated at their upper ends to permit the closed ends of the pipes to be inserted verticallj between the flanges which support the closed end of the pipes. against displacement, the end plate tat the opposite end of the, supporting frame being provided wane-510e, open at its upper end so as to permit the burner to be readily as- 'hot flame and substantially sembled in and removed from its supportingframe. The opposite end of the lowerpipe is closed by acap or plug 11, while '1 the upper pipe is provided with curved couplings to which the oil supply pipe 12 Patented Apr. 1, 1913.

is secured. Oil vissupplied to the upper pipe or tube from a tank 13 located su'fficiently above the burner to insure any desired heat or pressure of oil thereto, and the supply is regulated by means of a needle valve 14.

In the: particular embodiment illustrated I in'thedrawings, the lower pipe 5 is pro-' vided with two burners 16, each of which is formed by a pin hole 17, in the upper wall of the 'pipe'near its end, and oppositely inclined longitudinal grooves 18 are formed in the upper wall of the pipe and communieating with the pin hole, thereby permitting any unvaporized oil that may escape through the exitto collect in the groove and be consumed by the burner flame.

Y The upper pipe 6 is provided with-spreadf ers 19, each of which is located immediately overoneof the burners on the lower pipe and 'in such proximity thereto" that the I burner flame will impinge againstf the lower and upwardly inclined walls "20' of the spreader and be thereby transformed into an annular flame which may be used for cooking or other purposes. exceedingly perfect combustion of the oil is secured by the intimate admission of air to the, jet of' escaping oil through the circular openings 21. in the transverse deflecting plates 8, which insures a free inlet of air allaround and in intimate contact with the escaping jet of oil and gas. Spreaders 19 may be made of any'desired metal andsecured to pipe-6, or they may be cast integral therewith. They are of sufficient size, weight and shape to not only form an annular flame, but serve to absorb heat and assist in vaporizing oil flowing through the pipe and convert it into .flame Spreaders,

From the foregoing it will be noted that the oil burner is exceedingly simple in its construction and may be manufactured at small initial cost, as it is mainly composed of stock pi es or tubing and elbow joints which may e readily cut into any desired lengths and assembled for use.

The frame in which the burner is supported is rovided with closed side and end plates. an with a top plate which is closed at: all points excepting at the circular openings 21 and hence air which enters through the grate in which the burner is supported flows upwardly into the spacein the underside of the supporting frame and escapes therefrom through the openings 21 where it commingles with the oil and gases issuing through the burners and insures a perfect combustion and an exceedingly hot flame.

'While I have illustrated one embodiment of my invention it iseVidentthat it may be applied in various ways to ranges and stoves and hence, I would have, itjunderstood that I do not'restrict'myself to the particular construction shown and described.

Having fully described my invention what I claim as new and desire to secure by Lettars-Patent, is

1. The combination of an oil supply pipe thickened and enlarged at points to form a burner pipe connected with the oil supply pipe and provided with a burner for each flame spreader, each burner being located under its spreader, and a supporting frame comprising a top plate and two end members projecting above the top plate, one end member being slotted for the insertion of the oil supply pipe, and the other provided on its inner face with projecting at oaves;

flanges adapted to receive between them the coupling connecting the oil supply and burner pipes whereby the oil supply pipe-is maintained in position above the burner pipe:

2. An oil burner comprising an oil supply pipe and a burner pipe, the oil supply pipe being located vertically above the burner pipe and having a plurality'of separated solid bodies of metal integral therewith and the sides to form spreaders for the flame, and the burner pipe having exits for oil and gas, the said ex1ts being located under the flame Spreaders on the .oil pipe, and also having longitudinal grooves projecting in both directions from said exits.

3. The combinationof an oil supply pipe, a burner pipe, the latter being in the plane of and below the oil supply pipe, and provided with a burner, an elbow connecting the two pipes and aburner supporting frame comprising a top plate and side and end plates, the end plates projecting. above the top plate and one slotted to receive the oil pipe and the other provided on its inner face with parallel flanges to support the elbow connecting plate provided with an air opening located immediately under the burner on the burner pipe, and with deflecting surfaces at the sides of the air opening for deflecting the air upwardly to the burner.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
